Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

↔ Response Time Black to White

52.4 ms ... rise ↗ and fall ↘ combined

↘ 19.2 ms fall

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 99 % of all devices are better.This means that the measured response time is worse than the average of all tested devices (25.6 ms).

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 89 % of all devices are better.This means that the measured response time is worse than the average of all tested devices (41 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM not detected

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9254 (minimum: 43 - maximum: 142900) Hz was measured.

(±) The average temperature for the upper side under maximal load is 37.4 °C / 99 F, compared to the average of 30.9 °C / 88 F for the devices in the class Multimedia.(-) The maximum temperature on the upper side is 47.6 °C / 118 F, compared to the average of 36.4 °C / 98 F, ranging from 21.1 to 71 °C for the class Multimedia.(±) The bottom heats up to a maximum of 42.1 °C / 108 F, compared to the average of 38.8 °C / 102 F(+) In idle usage, the average temperature for the upper side is 28.4 °C / 83 F, compared to the device average of 30.9 °C / 88 F.(-) Playing The Witcher 3, the average temperature for the upper side is 38.1 °C / 101 F, compared to the device average of 30.9 °C / 88 F.(+) The palmrests and touchpad are reaching skin temperature as a maximum (32.2 °C / 90 F) and are therefore not hot. (-) The average temperature of the palmrest area of similar devices was 29.1 °C / 84.4 F (-3.1 °C / -5.6 F).
